Introduction: Sugar beet is one of the most important crops in the world and a major part of the sugar consumed in our country is obtained from this plant. Due to the limited area under cultivation, much research has been done regarding the increasing sugar beet yield per unit area. One of the important factors in sugar beet root production is the sowing date, which affects the duration of the vegetative and reproductive growth period and the balance between them, and ultimately affects its quantitative and qualitative yield, so one of the general policies of the agricultural sector is to increase the production of this product. For this purpose, this research aims to determine the most suitable sowing date and the most compatible variety in the region as effective agronomic methods in increasing the efficiency of sugar production per unit area.
Materials and methods: In order to investigate the effect of sowing date on yield and quality traits in three sugar beet cultivars, an experiment was conducted in the form of a split-plot in the form of a randomized complete block design in four replicates at the research farm of Gonbad Kavous University in 2018-2019. The main factor of sowing date in five levels including October 1st, October 15th, October 30th, November 15th, November 30th, and December 15th, and the secondary factor of cultivar in three levels including Monatunno, Rosagold, and SBSI 061, which was a total of 15 treatments in each. It was cultivated repeatedly.
Results: The results of the research showed that root yield, sugar, and white sugar yield were affected by the sowing date, and the first and the second sowing date, had the highest root yield, sugar, and pure sugar yield. Among the cultivars tested, there was no significant difference between Monatono and Rosagold in terms of root performance, but they were different from cultivar 061. In terms of sugar yield and white sugar yield, there was a significant difference between all three cultivars, among which Rosagold had the highest sugar yield and pure sugar yield, followed by Monatunno and finally 061.
Conclusion: The comparison of the averages of the experimental treatments showed that all cultivated cultivars would have the maximum sugar yield on the first and second sowing dates because simultaneous cultivation with effect during vegetative and reproductive growth period would absorb maximum solar radiation leading to an increase in the root yield and sugar. Finally, based on the examination of the results of this experiment and the analysis of information on the changes in quality traits, it is recommended to cultivate Rosagold and Monatunno cultivars in the first two planting dates to achieve the maximum sugar yield per unit area for the beet growers of Golestan province.
